BCC is an alternative ACS compiler.

function int f() {} // returns 0

If a function that returns a value reaches the end, and there is no “return” statement at the end, the function returns 0. This is done to avoid false compiler errors like this:

function int f(void)
{
    if (x)
        return 1;
    else
        return 2;
    
    // ACC will complain that the function doesn't return a value
}

BCC fails to mark named clientside scripts as clientside, so they end up actually being serverside. Instead, it marks an unnamed, not necessarily existing script as clientside.
